publicstaticvoid main ( String[] args ){
Runtime rt = Runtime.getRuntime();
String s="google.pl";
String ilosc_s;
String rozmiar_s;
String x;
//System.out.println("rozmiar:" +z+ "/n");
ilosc_s=JOptionPane.showInputDialog(null,"Podaj ilosc");
int ilosc_i;
int rozmiar_i;
rozmiar_s=JOptionPane.showInputDialog(null,"Podaj rozmiar");
ilosc_i=Integer.parseInt(ilosc_s);
rozmiar_i=Integer.parseInt(rozmiar_s);
System.out.println ("pingdas : " );
System.out.println ("pingsa : " );
System.out.println ("ping -n "+ilosc_i+" -l " +rozmiar_i+" "+s);
String d="";
try{
Process p = rt.exec ("ping -n "+ilosc_i+" -l " +rozmiar_i+" "+s);
System.out.println("Process done");
InputStream is = p.getInputStream();
BufferedReader rd =new BufferedReader(new InputStreamReader(is));
String str;
while((str = rd.readLine())!=null){
System.out.println ("ping:" + str);
d+=str;
}
System.out.println(d);
try{
BufferedWriter zapis=new BufferedWriter(FileWriter("plik.txt",true));
zapis.append("Jakis string");
}catch(IOException ex){
System.out.println("Błąd operacji na pliku: "+ex);
}
rd.close();
p.destroy();
System.out.println("done");
}catch ( Exception e ){
System.out.println ( e );
}
}
}
